Log:
SVN rev 184327 on 2008-10-27 08:40:13Z by kato
Improved IDE HDD geometry adjustment. Previous code didn't work with
certain ATA-6 drives including CF cards.
The IDE geometry of the PC98 is calculated from the drive capacity.
In addition to the algorithm in NEC BIOS, a variety of algorithms are
provided by 3'rd party boards and BIOS hacks. This change has
implemented the three algorithms: IDE BIOS compatible mode, SCSI BIOS
compatible mode and same way as the previous version. The tunable
machdep.ad_geom_method selects the algorithm.
I have been using this change for a year with CF cards.
